Do bathroom fans push air in or out?
Bathroom fans are designed to draw (pull) air into the bathroom and exhaust it out of the house. The fan draws air into the bathroom through the intake vent and pushes the heated, humid air through the exhaust vent to the outside of the house. This is why they are often installed in bathrooms that are close to the kitchen or other areas where cooking fumes can build up.
Some vent pipes are designed to be one way—in which case, they will push air out. Others are designed to be two way—in which case, they will suck air up.
If you’ve checked your exhaust vent pipe and found that it is clearly not blocked. This may be due to incorrect installation of the exhaust fan. If your fan is incorrectly installed, then it may be blowing air downward instead of exhausting it upwards.
This is often due to the height difference between the intake and exhaust vents. The height difference could also be due to a lack of air pressure differential. You can check your exhaust vent pipe for these problems by turning off your fan and feeling which direction your finger is being pushed by air coming out of the pipe.
If you find that air is being pushed down, this means that something is wrong with the vent.
